If I were to take your question seriously, and not just a slam on Melania Trump which it probably is, I would say that it might be hard to keep "conflict of interest" stuff out of it and the secret service would have an additional big job on its hands. I don't profess to know details, but I have heard in passing that Trump needs to bow out of his businesses while he is in the White House. The whole management has been turned over to the kids while he is in office, if that happens. Now, if the Pres is not supposed to be working outside the WH, why would his wife be allowed to (or her husband, if Clinton becomes President)? Did I get that wrong?
